Aggressive forms of adult T-cell leukemia (ATL) respond poorly to conventional anticancer chemotherapy, and new lead compounds are required for the development of drugs to treat this fatal disease. Recently, we developed ATL cell-selective proliferation inhibitors based on a tetrahydrotetramethylnaphthalene (TMN) skeleton 1, and here we report the design and synthesis of silicon analogs of TMN derivatives. Among them, compound 13 showed the most potent growth-inhibitory activity towards the ATL cell line S1T, though its selectivity for S1T over the non-ATL cell line MOLT-4 was only moderate. This result, as well as computational studies, suggests that sila-substitution (C/Si exchange) is useful for structure optimization of these inhibitors.
侵袭性成人 T 细胞白血病(ATL)对传统的抗癌化疗反应不佳,因此需要新的先导化合物来开发治疗这种致命疾病的药物。最近,我们开发了基于四氢四甲基萘(TMN)骨架 1 的 ATL 细胞选择性增殖抑制剂,在此我们报告 TMN 衍生物硅类似物的设计与合成。其中,化合物 13 对 ATL 细胞株 S1T 的生长抑制活性最强,但与非 ATL 细胞株 MOLT-4 相比,其对 S1T 的选择性仅为中等。这一结果以及计算研究表明,硅取代(C/Si 交换)有助于这些抑制剂的结构优化。
